  An object of the present invention is to provide a liquid-crystal display element using a liquid-crystal composition having negative dielectric anisotropy, capable of realizing excellent display characteristics by being used in an FFS mode liquid-crystal display element, without deteriorating various characteristics as a liquid-crystal display element such as dielectric anisotropy, viscosity, a nematic phase upper limit temperature, nematic phase stability at low temperatures, and γ1, and burn-in characteristics of a display element. A liquid-crystal display element containing at least one compound selected from the group consisting of compounds by the following General Formula (I) is provided: wherein each of R1 and R2 independently represents an alkyl group having 1 to 8 carbon atoms, an alkenyl group having 2 to 8 carbon atoms, an alkoxy group having 1 to 8 carbon atoms, or an alkenyloxy group having 2 to 8 carbon atoms, A represents a 1,4-phenylene group or a trans-1,4-cyclohexylene group, k represents 1 or 2, and in a case where k is 2, two A's may be the same as or different from each other.

  本发明的目的是提供一种使用具有负介电各向异性的液晶组合物的液晶显示元件，该液晶组合物能够通过用于全氟辛烷磺酸模式液晶显示元件而实现优异的显示特性，同时不会降低作为液晶显示元件的各种特性，例如介电各向异性、粘度、向列相上限温度、向列相在低温下的稳定性和γ1，以及显示元件的烧损特性。本发明提供了一种液晶显示元件，其中含有至少一种选自由以下通式（I）化合物组成的化合物组的化合物： 其中 R1 和 R2 各自独立地代表具有 1 至 8 个碳原子的烷基、具有 2 至 8 个碳原子的烯基、具有 1 至 8 个碳原子的烷氧基或具有 2 至 8 个碳原子的烯氧基，A 代表 1，4-亚苯基或反式-1，4-环己烯基，k 代表 1 或 2，在 k 为 2 的情况下，两个 A 可以相同或不同。
